> As an example, I have been looking at CouchDB,
which uses JSON.
> Brief summary of CouchDB:
>
> Â Â 1. A B-tree manager whose records are JSON
expressions.
>
> Â Â 2. Open-source, available from Apache, with
bindings to all common
> Â Â Â programming languages, including _javascript_
and PHP.
> Â Â Â
http://couchdb.apache.org
>
> Â Â 3. An HTTP interface for queries and updates,
which uses map-reduce
> Â Â Â to take advantage of as many CPUs as your
server may have.
>
> Â Â 4. Documented by an O'Reilly book with a draft
available for free:
> Â Â Â
http://guide.couchdb.org/draft/index.html
>
> At the end of this note is a sample JSON _expression_
used by CouchDB.
> Any quoted string could be a URI or it could be raw
data of any length.
>
> Suppose that you were a programmer working at a
library, and your boss
> asked you to convert the entire library catalog to
Linked Open Data
> and make it available via HTTP.
>
> If you chose Couch DB, you could
>
> Â Â 1. Read the O'Reilly book.
>
> Â Â 2. Download and install CouchDB.
>
> Â Â 3. Write a trivial program to map each record in
the library catalog
> Â Â Â to a JSON _expression_ very similar to the
example below.
>
> Â Â 4. Write a program to download every record from
the library
> Â Â Â catalog, convert it to JSON, and store it in
CouchDB.
>
> Â Â 5. Write a web page that tells any web master
anywhere in the world
> Â Â Â how to write an HTTP statement for accessing
that DB.
>
> With CouchDB, you could finish that job in one
week. Â What could you
> do with RDF and currently available tools?
>
> Of course, there is no requirement that the strings
in JSON conform
> to any particular ontology. Â But that is also true
of RDF.
>
> JSON makes it easy to tag URIs with types. Â In the
following example,
> anything on the left of a colon ":" could be a type
in the ontology.
> That's more readable and more compact than RDF.
 One JSON structure
> also takes one DB access -- much, much less than
multiple RDF triples.
